I encounter a strange behaviour in my Spring-Boot project (v4.0.6):When I execute a Controller which retus ResponseEntity<StraingResponseBody> for writing NDJSON-Lines the FilterChainProxy of SpringSecurity will get invoked twice. In the second invocation it looses the previous resolved Authentication object and throws an error.The Controller is defined as such:@RestController public class AsyncController { private Logger logger = LoggerFactory.getLogger(AsyncController.class); ادامه مطلب

I have a Docker container with OrbStack that contains a directory repos with a repository app-main and worktrees like app-feature-a to develop in parallel. Configuration is done in order to prevent modification of the container configuration file in the ruing Docker. project/ ├── .devcontainer/ # outside the mount, on purpose │ └── devcontainer.json └── repos/ ├── app-main/ ├── app-feature-a/ └── app-feature-b/ MWE for devcontainer.json : { "name": "myproject", "image": ادامه مطلب

We would like to use Hibeate StatelessSession injected into our Spring Data JPA repositories. Our understanding is this requires HibeateTransactionManager and SharedSessionCreator.createSharedStatelessSession. Our setup is like follows: @Bean public HibeateTransactionManager transactionManager(EntityManagerFactory entityManagerFactory) { var hibeateTransactionManager = new HibeateTransactionManager(entityManagerFactory.unwrap(SessionFactory.class)); retu hiberادامه مطلب

I created a file with one line "bug line", initialized git repository and committed change. Then I added the second line "staged" and staged the change. Then I added the third line "unstaged". How to add a commit changing the first line to "bug line changed" so that I still get the second line as staged change and the third line as unstaged change without merge conflicts?

I was reading a (quite old) book on POSIX API, and in the chapter on threads it says that on retu from main() all the threads (including detached ones) are terminated. I would expect that std::thread::detach() inteally uses POSIX threads API, and yet it seems that a detached std::thread is sort of joined with the main() thread (or the main process really), after the main() function retus on Ubuntu 26.04. For example, the code below blocks on a read from std::cin and, if I write anything ادامه مطلب

I get this error, if I click my script multiple times: Uncaught (in promise) Error: reCAPTCHA has already been rendered in this element. I know, that error is correct, but how can I fix this? I have got a cookie-icon that shows a baer to accept or to reject the recaptcha/form. I hide or show the recaptcha/form onclick, but if the user clicks multiple times the accept button i get this error in console and he can not send the form. Hard to explain here is my code :) Edit: Here is a jsfiddle: ادامه مطلب

I'm writing a query in Oracle SQL. I'm using a count - group by query, for example:

select column_a, count(*)
from table_1
group by column_a

COLUMN_A    COUNT(*)

value_1     5
value_2     6
value_3     2
(null)      1

Can I write a group by that allows me to get two result rows, one with value_1 and its count, and another with the count of all other values? It would look like this:

COLUMN_A    COUNT(*)

value_1     5
others      9

The following code snipped defines a nested chain of templated C++ classes. The problem I have starts on the third level. The initialization of the three level nested class works well, which can easily checked in a debugger. However, a problem arises when attempting to access the nested class member variables aValue. While the first two levels work well, accessing third level aValue gives me no joy. Any suggestions on how to propagate variable access down the chain? Ideally, is there any iteratoادامه مطلب

I'm working on a Laravel project and I need to search through 2 models as the same time. I decided to use a union for this query, as I would do it in SQL. One of my models is converted into the other, and then the two queries are unioned. I was expecting to be able to filter as well after that, but any where clause I'm using ends up applying only on the first part of the union, and not the second. Here's the code EntityMember::union( User::select(*convert User into something similar to Entitادامه مطلب

I am having trouble compiling a C program that uses a shared library.

When working with keyboard input in a situation like the one shown in the next simplified example: // abc.hpp #pragma once #include <array> // ranges of integer values in the enum could be contiguous or // not, so question is for a general scenario. However if being // a contiguous range of integer values makes things notably // simpler, then certainly it'd be interesting to know about it. enum FileType : int { JSON = 1, YAML = 2, XML = 3 }; constexpr std::array<FileType, 3>ادامه مطلب

I am trying to make a small robot with raspberry pi 3, Arduino uno and python sockets.

I'm leaing Python and using VS Code (Windows). I wanted to clear the terminal from the long paths when ruing code, so I installed Code Ruer and went to Settings -> Executor Map, and changed python map from "python -u" to "clear && python3 -u". But when I run code, I get what's in the picture instead of execution result. (There's nothing in output console either.)

I am working on improving the SEOP of an e-shop built as a React SPA. (I know its bad). The e-shop contains products that have one main Manufacturer Part Number, but some products can also have one or more alteative manufacturer part numbers. I need to make sure that wehn people search on Google using one of these alteative part numbers, Google can associate the alteative number with the correct product and show the corresponding product page in the search results. For example, if a producادامه مطلب

I'm trying to lea graphics programming. Currently, I'm trying to make my camera look at the world origin at (0, 0, 0), but I can't understand why this operation is inverted for the camera. For example, if I have a camera at (0, 0, -5), it tries to look at (0, 5, 0). Instead of looking at the desired position, the camera looks at the inverted position at (0, -5, 0).

Here's the code implementation for the context:
